摘　　要：为实现感应电能传输(Inductive Power Transfer,IPT)系统在变负载条件下的恒流/恒压高效输出,提出一种基于频率切换的LCC-S型IPT系统参数配置及优化方法。从LCC-S补偿拓扑入手,分别得到系统恒流或恒压零相位角(Zero Phase Angle,ZPA)输出的条件方程,并推导了电流增益、电压增益与系统参数之间的定量关系;进一步通过定义系统的输出增益比,分析了恒流/恒压模式下输出增益、负载电阻与整体效率的关系;在此基础上,通过选取最佳的输出增益值,使得系统整体效率达到了全局最大化。仿真结果表明,负载电阻在3~300Ω的变化范围内包括恒流/恒压模式切换瞬间都能保持稳定的输出,并且恒流/恒压模式下均能实现ZPA运行,同时系统整体效率都维持在90%以上。To achieve constant current/constant voltage high-efficiency output of inductive power transmission(IPT)system under variable load conditions,a parameter configuration and optimization method of LCC-S IPT system based on frequency switching is proposed.Starting with LCC-S compensation topology,the conditional equations of zero phase angle output at the constant current or constant voltage are obtained respectively,and the quantitative relationship between current gain,voltage gain,and system parameters is derived.Further-more,by defining the output gain ratio of the system,the relationship between the output gain,load resistance and the overall efficiency in the constant current/constant voltage mode is analyzed.On this basis,the overall efficiency of the system is maximized by selecting the op-timal output gain value.The simulation results show that the load resistance can maintain a stable output in the range of 3~300Ω,inclu-ding the instant of constant current/constant voltage mode switching,and ZPA operation can be achieved under constant current/constant voltage mode,while the overall efficiency of the system is maintained above 90%.
